AFE7950-TRF1208-EVM Evaluation Module User's Guide

The evaluation module AFE7950-TRF1208-EVM is used to evaluate the performance of TI's AFE79xx family of integrated RF sampling transceivers with TI's TRF1208 differential amplifier. The AFE79xx devices support up to 4 transmit, 4 receive, and 2 feedback channels (4T4R2F) and integrates phase-locked loop (PLL) and voltage-controlled oscillator (VCO) for generating data-converter clocks. The AFE79xx device integrates 8 JESD204B- and JESD204C-compatible serializer or deserializer (SerDes) transceivers capable of running up to 29.5 Gbps to transmit and receive digital data through the onboard FPGA mezzanine card (FMC) connector.

TRF1208 device is a D2D (diff-to-diff) amplifier that either drives the ADC of receive paths (in S2D configuration) or are driven by the DAC of the transmit path (in D2S configuration). The EVM includes the LMK04828 clock generator to provide reference clocks and SYSREF to the analog front end (AFE) and capture card (field-programmable gate array, FPGA). The evaluation module (EVM) works off a single 5.5-V input and includes complete power management circuitry. External clocking options include support for feeding the reference clock (for the on-chip PLL). The design interfaces with the TI pattern and capture card solution (TSW14J56 and TSW14J57), as well as many FPGA development kits.
